3-Methyl-7-(2-oxo-2-phenylethyl)-6,7-dihydro-5H-imidazo[2,1-b]thiazol-4-ium bromide CAS 139313-11-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methyl-7-(2-oxo-2-phenylethyl)-6,7-dihydro-5H-imidazo[2,1-b]thiazol-4-ium bromide.

3-Methyl-7-(2-oxo-2-phenylethyl)-6,7-dihydro-5H-imidazo[2,1-b]thiazol-4-ium bromide (CAS 139313-11-4), molecular formula C14H15N2OSBr and molecular weight 339.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 3-Methyl-7-(2-oxo-2-phenylethyl)-6,7-dihydro-5H-imidazo[2,1-b]thiazol-4-ium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-Methyl-7-(2-oxo-2-phenylethyl)-6,7-dihydro-5H-imidazo[2,1-b]thiazol-4-ium bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
